To all whom it' may concern:

it lino'svn that We, Cnnnnss linnnuio'r and ARTHUR Scnivnnznorr, both'citizens of the United States, and both residing nt Chicago, in Iliecounty of Cook and tete of Illinois, have invented certain new enduseful Improvements in Barbers Chairs, of which the following is a.speciication.

The present invention relates more pan ticularly to the locking devicesfor holding the back and foot rest of the chair in edjnsted position,and to the le mechanism for actuating said devices and for operating,rthe pump employed in raising and lowering the chair. Y

The present invention relates hydraulic berbere chairs in which a leveris provided at the side of 'the choir for opto e type of Speoicaton or'Letters Patent."

ersting the pump, and the object of the present invention is to alsoprovide, in connection with the lever, a suitable device, or devices,for releasing the'rod which controls the reclinin movements of thechair. In the past, diculty hasfbeen experienced in uniting thesevarious adjusting devices into n single lever mechanism adapted to heeasily and. conveniently grssped and controlled by the barber with onehand While manipulatingg,v the chair with the other.

The object of the presenty invention is to so construct,arrenge .andunite 4the various adjusting niechanisinsthet a. single lever can neemployed for e'ecting all of the op.. erctions necessary in themanipulation of a. harners chair, 'without lditiiculty and in nn easy,convenient and natural manner.

The invention further relates to the clamping devices employed forholding the lock bar, Whicn serves to hold the parts in usted position;to the rod and lever mechcnisni `for actuating said clamping; devices;to the construction and ,nrrangement of the I pump bucket,niilierebyzineans vill he afforded for locking thecheir against revolntion; to tlielsncket actuating rod 'and conf nections with the handlever; and to the chair .as s Whole and the individual ports `Furtherobjects Will appear from a de tniled description of the invention, whichconsists in the features of const-motion and combination of partshereinafter described end claimed.

The chair is of a standard type, compris ing a body portion 10, a backll, an apron l2, and a foot rest 13 of the style commonly found inharbors choirs. The bod7 portion has rigidly secured thereto, on eachside, a pair of 'side arms lei. which extend above the body portion econsiderable distance. To the inner sides ot the erins ere pivotedhanger brackets l5, the lower ends or which nre rigidly secured to thesides of the npron. The hack is provided, at' its lower end on eachside, With a bracket plate 16, which forwardly entends from the bach andis provided, nee-r its opper corner, Wit-li a pivot hole l?, whichreceives apivot pin or stud, not shown, which inwardly projects from theediecent side arm, neer the rear end thereon and serves to pivot thehack loetween the rigid therethrough a pivot stud 18 which servos to`pivot the .bracket plate to a hanger 19 imtvardly projecting from therear corner ofen open seat frame 2O which is pivoted to the oyeronhenger 'craclrets lo. The seet freine 20 serves as s mounting-for aseat' cushion 2l of the usuel style. The construction is one which pivotelly unites the seat With the heck and a Jron in such manner that anyadjustment ol the hitch, out of the vertical, will be confinruni-v catedthrough the seatrsrne to the'itoron, and vice versa. This arrangement o1parts is Well understood end need not be further detailed. I

The apron l2 has secured to its rear or inner.l side e bracket 22, tovvni e rearwardly extending loch of the pump bucket; Fig. 7 en enlargedcross sectional view of sides of the choir. EachA vot the bracketplates, near its lower outer corner, han; entered the type sometimesemployed in barbers chairs,l which rod, as shown, is of circularformation and is entered through a cylindr-zl guide block Q4: having aninwardly extending cylindrical neck of reduced dianictenV which necklinds a bearing' in a cylindrical hole QG formed through the side wallof the main bracket head Q", from which depends the cylindrical stem 2Swhich mounts the chair. The bracket head is hollow on its interior toafford a chamber 29, and the upper edge of the bracket is provided withflanges 30 which support the body ot the chair seat. The neck 25 of theguide block'is swiveled within the opening 26, and the body portion otthe guide block proljects outwardly therefrom in position to have thelocking rod passed' dialnetrically through its center. The neck isheldagainst retraction by means of a set sere ,v Bl, the end ot' which isentered into a cir-Quinterentially extending groove or channel near theinner end of the neck rIhe arrangement is one which atfords theneccesary turning movement or oscillation of the guide block toaccommodate the locking rod, which oscillates to a slight degree byreason of the. swing of the apron.

The center of the guide block is cored out to attord a cylindricalchainber 133, within which is located a pair of clamping plates 3l,through which plates the locking rod is entered. rthe clearance tor therodv is so slight that it can be reinoved longitudinally only when theplates are held in parallel relation, as shown in Fig. When in thisposition the holes in the plates will he brought into exact alineinentand register, so that tl e rod can be nioved hack and t'orth through theholes without clamp# ing or binding against the edges thereof. il'hen,however, the plates are lthrown out or oaralle-lisxn, as shown in Fig.4, the edges of the holes will impinge or bite against the rod and chnnpit in any desired position ot adjustment. Each of the clamping plates,at its inner end, is beveled, as shown at 35, the beveled ends being inContact with the beveled inner faces 36 of a recessed wedge block 3T,which is in the form ot a at disk tilted into the inner end ot' thechamber 333 and provided with an inwardly extendingY stud 38 which isentered through a hole il!) in the neck of the guide block. The hole 3f)is counlerhor-ed to attord a circular recess lo which receives a washer4i, :itdjaccnt to which lies the end ot the tubular rock `shaft d'2,which end tinds a bearing within a washer 43, which abuts against theinner end orn the neck 25 and is ot' equal size therewith. The tubularrock shaft is provided, near its inner end, with a shoulder 4i.. whichbears against the outer tace of the washer #t3 and prevents displacementof the washer which is`held within the inner end of the hole 26 in thewall of the bracket head.

'lhe tubular rock sli-att a'tifords a housing for a longitudinallv iovahle operi 'i L15, the inner end ttf ot i i` within the washer l t nwed a shoulder l? which nears ao' inst the rod. @the end oli the rod isedili abut againstaud outwar .ly project tine rc- .7.. cessed wedgeblock 3l" te tue extent necessary to cause the inner heveletfi tacos ot'the wedge block to engage the beveled faces olii the clamping pates andthrow the latter into parallel relation against the tension of 8G aninterposed spring 49. rEhe recess in the guide block 2i covered andinclosed hy ineans ot a cap 50 provided, in its center with a recess 5l.which holds the ends ot the clamping plates. Sg

The operating rod extends, throughout its length, within the tubularrock shaft, and its end is entered within a cliainhered head 52, whichpreferably vintegrally termed on the .end ot' the tubular rock shaft.'the 90 head has 'formed thereon an upwardly eii tending sleeve whichatliords a mounting for a lever rod Bel, tcrniiiiating in a handleprovided, on-one side, with a laterally e1;- tending linger .3G ot i :cand length sul'ti- Y 95 cient to allot-d an eas)y and comfortable eu-'ageiuent for the hand ot the user.

'lhe tubular rock sha'tt providml, near 115 its center, on its upperside, with au ear GO .which receives the forked end (il ot a pump pistonrod (32,. the parts being` pivoteijl i gether bv means ot a pivot pin13. il pump' ton rod olls near upper eno.. to clear the tuhular ro.shaft around which ity extci'ids. and forked at its lower end Gill andente t into the open upper end ot a, pulnp bucket, between the walls ofwhich it pivotcd, inf means ot a cross piu titi. rlfhe 325 bucket is otgenerally cylindrical shape and tits closelyv within the c vlinth'iealstern "y which stein is slidahlgv` and rotatanly mounted within acylindrical well 6T, ornr ing part of the base et the chair. The iii-per3o end 68 of the bucket, on its outer side, is slightly beveled ortapered to engage with a pair of wedge blocks 69 which are enteredthrough slots 7() cut across the cylindrical wall of the stem onopposite sides thereof. The wedge blocks are of the form shown in Figs.7 and 8, having a rounded outer face 71, which has a curvaturecommensurate with that of the cylindrical 'stem within which it ispositioned.'` and having an inner fiat face 72, save in the center,where said face is eut away by an upwardly tapered' cylindricalconcavity 7 3. The ends 7e of the block are wedge shaped, with theresult that, when the bucket is raised to a predetermined height, itstapered upper end will engage the recessed portion of the wedge blocksand force the blocks outwardly, so that the rounded faces of the wedgeblocks will bear against the wall of the surrounding well, therebylocking the stem against revolution and affording an extended contactingsurface.

The bucket isA provided with a floor 75 having a centrally located valveopening 76, the under edges of which are beveled to afford a seat for aspring controlled inner valve 77, the stem Iof which projects through abottom plate 7S. The lower end of the tubular stem is shouldered toafford an enlarged chamber 7S), 'in the floor of which is a valveopening 80, the under edge of which is beveled to afford a seat for aspring controlledouter valve 8l, the stem of which projects through andis guided within an outer plate The well, near its lower end, isshouldered to afford an enlarged chamber 83, which is closed by means ofa plugged bottom wall Si. The well is pio vided with a flange 85, whichrests upon an annular boss Sli which projects from. a circular baseplate 87 which rests upon the Hoor. The bucket is provided, near thelower end of its inner chamber, with one or more diagonally disposedvent openings S8,

so arranged that when the bucket is in its' lowermost position they willcommunicate with the enlarged chamber 79 in the bottom of the well.

In use, when it is desired to recline the chair, the operator grasps thehandle of the lever and gives a partial turn to the same by pressingagainst the laterally projecting finger, which turning movement willcause lthe edge of the fiat faced notch 58 to iinpinge against theoperating rod 45 and in' Wardly project the same, therebydrawingtogether the inner ends of `the clamping plates, which willnormally occupy an ontwardly convergent position,- as shown in Fig. 4.This action serves to release the plates from clam ing engagement withthe locking rod, there y allowing the'chair to be This adjustment can beeasily effected by the barber,

pump bucket, the

who is enabled to grasp the back of the chair with his left handwhileoperating the .lever handle with his right hand. As soon as the leverhandle is released, the pressure of the spring 48 against the operatingrod will throw back the rod and turn the lever handle to normalposition, thereby releasing the clamping plates from engagement by therecessed wedge block, which againdocks'the chair in adjusted position.When it is desired to raise the chair, the lever handle is rocked oroscillated back and forth, which reciproeates the pumpvbuckct and pumpsthe oil or other liquid contained in the tubu lar stem out into thewell, thereby raising the chair. lVith each upward stroke of the openedby the pressure of the oil to permit the down-flow will be dischargedthrough the lower valve by the next down stroke of the pump bucket, andthis process will ,continue until the chair has been elevated to thedesiredA degree. Thereafter, when the lever is moved to 'its normal or'vertical position, the bucket will be lifted to its extreme positionand brought into engagement with thewedge blocks 72, which are spread tothe extent. necessary to bring their outer faces into locking contactwith the walls of the well, so that the chair will be locked againstrotation. A slight movement of the lever in the forward direction willbe suiicient to release the wedges and peinit rotation of the chair,without either raising or lowering the same. When it is desired. tolower the chair, the lever will be thrustdown to its lowermost position,thereby forcing down the bucket until the Vent openings 8S are broughtinto comninni cation with the enlarged chamber S5 at the bottoni of thewell and the bucket forces down and opens the valve 81, at which time`the oil will have free cmnmunica'tion through the valve and escapethrough the vent openings, and into the tubular stem of the chair,allowing the latter to gradually descend to the desired point.

The arrangement of the lever handle is such that the barber can.manipulate the lever inany desired manner without shifting the positionof his hand or body and without any material exertion, leaving his otherhand free for 'the manipulation of the chair. Furthermore, the leverhandle can be turned and the chair reclined at any position in thestroke of the lever, which is highly desirable, in that it relieves thebarber from the necessity of carefully bringing the lever to adesignated position of adjust ment before releasing the lock. p l

It Awill be seen that the lock operating and pump operating mechanism isso coinbined that an extremely simpleand easily manipulated adjustingmechazmsm 1s afof a quantity of oil, which inner valve 77 will be iforded, which is of great importance in the `i3o nan's.
